The trouble with public Wi-Fi
Open networks in airports, cafes, and hotels are shared by strangers, and many are unencrypted. That makes it easier for someone on the same network to intercept traffic, and it opens the door to fake hotspots set up to look legitimate. For casual browsing it is usually fine. For logging into your bank, your email, or work systems, you are trusting a network you know nothing about.
How a tethered eSIM compares
| Factor | Citrus Mobile eSIM (tethered) | Public Wi-Fi |
|---|---|---|
| Who else is on it | Only your devices | Strangers, sometimes many |
| Snooping risk | Low, private connection | Higher on open networks |
| Fake network risk | None | Real, lookalike hotspots exist |
| Speed at peak times | Steady, your own link | Often slow and congested |
| Availability | 200+ countries with coverage | Only where offered |
| Logins and captive portals | None | Often required, sometimes sketchy |
Security, in plain terms
A mobile connection is private to your device in a way open Wi-Fi is not. When you tether your laptop to a phone running a Citrus Mobile eSIM, no strangers share that link, and there is no captive portal harvesting your details. It is not a replacement for good habits like using a VPN and checking for HTTPS, but it removes the single biggest weak point, which is the untrusted network itself.
A simple rule
Use public Wi-Fi for reading the news. Use your own tethered connection for anything with a password, a payment, or work data. The cost of a little mobile data is small next to the cost of a compromised account.
Speed and reliability too
Security aside, public Wi-Fi is often slow at exactly the wrong moments, like an airport at peak hours or a hotel in the evening when everyone is streaming. Your own connection does not get divided up among hundreds of guests. On good 4G or 5G it is frequently faster and far more consistent than the free network. See laptop internet while traveling for the wider picture.
What it costs to stay private
Pay as you go from $4, with rates that vary by country, on the rates page. Keeping a topped up Citrus Mobile eSIM ready means you can avoid risky networks whenever it matters, for very little. The pricing page has the details.
